The cities extension, request for developing and increasing underground transportation system. One of this ways in big cities is urban tunnels or metro. Tabriz often located on alluvial deposits, so these tunnels repose in these deposits. In this study we investigate engineering geology aspects of Tabriz Metro line 2, approximately 22 km long. Then it is described about natural temperature measuring of ground layers, and effect of this temperature in metro construction and using. Ground natural temperature is depended on atmosphere temperature and mineralogy of soil and groundwater condition. Some of clayey minerals are radioactive and increase ground temperature. Also, groundwater flowing may affect the ground natural temperature. In metro construction for tunnel boring machine (TBM) and exploitation of tunnel, knowing nature temperature is necessary. In this study, ground natural temperature is measured between 15 and 25 m depth. These measuring shown that the ground natural temperature is between 13 and 18 degrees C.

A NUMERICAL ASSESSMENT OF ATMOSPHERIC BOUNDARY LAYER SIMULATION INSIDE TWO DIFFERENT BOUNDARY LAYER WIND TUNNELS Abdulrahim, Anas; Elfarra, Munir; Uzol, Oğuz (null; 2019-09-20) A new large scale wind tunnel is under development at METU Center for Wind Energy (RÜZGEM). This wind tunnel is a closed-loop multi-purpose wind tunnel with a 3 m x 7 m x 20 m boundary layer test section. Inside this test section the atmospheric boundary layer (ABL) will be simulated using the spire-roughness element technique in order to represent different terrain exposures (or categories) as defined by American Society of Civil Engineers (ASCE). Since no experimental data are available yet, Computational...
Evaluating the Relation Between Station Area Design Parameters and Transit Usage for Urban Rail Systems in Ankara, Turkey Ozgur-Cevher, Ozge; Altintasi, Oruc; Tüydeş Yaman, Hediye (Springer Science and Business Media LLC, 2020-08-01) Urban rail transit (URT) systems are particularly favoured by planners due to their potential in attracting car users. However, a URT investment must be complemented by land-use characteristics at macroscale (whole city) and design parameters at microscale (vicinity of the station). Despite the common referencing to key concepts (i.e. density, diversity and connectivity), the variability in their definitions and scales causes ambiguity in the determination of their quantified impact on URT ridership. Furthe...
Assessing the Link between Rail Transit Usage and Multimodal Integration Özgür Cevher, Özge; Altıntaşı, Oruç; Tüydeş Yaman, Hediye; Babalık Sutclıffe, Ela (null; 2016-01-08) Current planning literature considers rail transit usage a function of neighborhood design (ND) parameters (such as density, diversity and connectivity) around station areas at a micro-level. However, during the early development stages of a rail transit system in a city, integration with the other modes may be equally influential on the rail transit usage, which must be determined. For this purpose, ridership data of 14 rail transit stations were evaluated based on both i) ND design parameters and ii) mult...
Exploring critical success factors for blockchain-based intelligent transportation systems Çaldağ, Murat Tahir; Gökalp, Ebru (2020-01-01) Utilization of Intelligent Transportation Systems (ITS) provides increasing demands on decreasing traffic congestions, transportation safety, and environmental problems as well as increasing transportation capacity. Over the past few years, one of the most disruptive and transformational technologies, blockchain technology, has emerged. As a result of offering more security, privacy, traceability, transparency, and decentralized authority, the utilization of blockchain technology in ITS have increased drast...
A comprehensive parametric study on the performance of seismic-isolated bridges Dicleli, Murat (null; 2006-07-16) This paper presents the effect of isolator and substructure properties as well as the frequency characteristics and intensity of ground motion on the performance of seismic-isolated bridges (SIBs) and examines some critical design clauses in the AASHTO (American Association of State Highway Transportation Officials) Guide Specification for Seismic Isolation Design. For this purpose, a parametric study, involving more than 800 nonlinear time history analyses of simplified structural models representative of ...
